Question

I have a portlet application. It is configured using Spring framework IoC container. I am using org.springframework.web.context.ContextLoaderListener to load my context.

I have an application context at root level (applicationContext.xml) and a portlet specific context (MyPortlet-portlet.xml).

I have a portlet of type org.springframework.web.portlet.DispatcherPortlet which is wired up to a Controller. In the Controller I want to access one of the beans (e.g. bean with id “myBean”) I have defined in my portlet specific context. I have tried

MyBean mybean = (MyBean)PortletApplicationContextUtils.getWebApplicationContext(
    getPortletContext()).getBean("myBean")

However only the beans in my application context are available here – none of my beans in my portlet specific context are available.

Is there a way to access the beans in my portlet specific context?

Thanks

Firstly, can’t you just wire in the bean to your controller in the normal way, rather than retrieving it programmatically?

Failing that, you should realise that getWebApplicationContext() gets a reference to the root webapp context, not the servlet app context:

Find the root WebApplicationContext
for this portlet application, which is
typically loaded via
ContextLoaderListener or
ContextLoaderServlet.

If your controller needs a handle on its own context, then it should implement ApplicationContextAware or BeanFactoryAware, or it can use @Autowired ApplicationContext if you want to use autowiring.
